Abstract

A new approach for the realization of a quantum interface between single photons and single ions in an ion crystal is proposed and analyzed. In our approach the coupling between a single photon and a single ion is enhanced via the collective degrees of freedom of the ion crystal. Applications including single-photon generation, a memory for a quantum repeater, and a deterministic photon-photon, photon-phonon, or photon-ion entangler are discussed.

Bradley K. Mitchell, Ravi K. Naik, Alexis Morvan, Akel Hashim, John Mark Kreikebaum, Brian Marinelli, Wim Lavrijsen, Kasra Nowrouzi, David I. Santiago, Irfan Siddiqi

Summary: In this study, a tunable ZZ interaction between two fixed-frequency and fixed-coupling transmon qubits is achieved, with adjustable coupling range larger than static coupling and changeable sign of interaction. This interaction is suitable for large quantum processors, with flexible drive frequency choice and resilience to microwave cross talk, enabling the implementation of a controlled phase (CZ) gate with high fidelity.

Room-Temperature Strong Coupling Between a Single Quantum Dot and a Single Plasmonic Nanoparticle

Jun-Yu Li, Wei Li, Jin Liu, Jie Zhong, Renming Liu, Huanjun Chen, Xue-Hua Wang

Summary: By integrating a single quantum dot with a single gold nanorod, the strong coupling between quantum dots and plasmonic nanoparticles has been achieved, opening up a new pathway for solid-state quantum information processing. Utilizing a wedge nanogap cavity, the plasmonic electric fields were effectively confined in the nanoshell of the quantum dot, leading to the largest spectral Rabi splitting reported so far.

Optomechanical strong coupling between a single photon and a single atom

Javier Arguello-Luengo, Darrick E. Chang

Summary: The study proposes a novel approach to achieve optomechanical strong coupling by coupling atomic motion to the cavity-dressed atomic resonance frequency. It shows that the scattering properties of single photons from the atom-cavity system become highly entangled with the atomic motional wave function. Additionally, the research analyzes some prominent features of optomechanical strong coupling, such as significant per-photon motional heating and mechanically-induced oscillations in time of the second-order correlation function of emitted light.

Multimode Strong Coupling in Cavity Optomechanics

P. Kharel, Y. Chu, D. Mason, E. A. Kittalaus, N. T. Otterstrom, S. Gertler, P. T. Rakich

Summary: This paper demonstrates strong coupling in a Brillouin-based bulk cavity optomechanical system, showing efficient, high-bandwidth, and deterministic transfer of quantum states as well as control of mechanical motion. By creating hybridized photonic-phononic modes through mode hybridizations, the system exhibits significantly longer lifetimes than an uncoupled system. Additionally, the bulk-acoustic-wave resonators supported phonons in this system have properties such as high frequencies, long coherence times, and robustness against thermal decoherence.

Coupling, lifetimes, and strong coupling maps for single molecules at plasmonic interfaces

Monosij Mondal, Maicol A. Ochoa, Maxim Sukharev, Abraham Nitzan

Summary: The interaction between excited states of a molecule and excited states of a metal nanostructure leads to hybrid states with modified optical properties. The condition for strong coupling between plasmons and molecules can be easily satisfied if the only contributions to the spectral width are associated with the radiative and nonradiative relaxation of a single molecular vibronic transition. However, the observation of Rabi splitting becomes more challenging when the molecule-metal surface distance is varied due to the spectral shift associated with the same molecule-plasmon interaction.

Strong Coupling of an Fe-Co Alloy with Ultralow Damping to Superconducting Co-planar Waveguide Resonators

I. W. Haygood, M. R. Pufall, E. R. J. Edwards, Justin M. Shaw, W. H. Rippard

Summary: This study reports a strong coupling between a metallic ferromagnetic thin-film element and superconducting waveguide resonators, demonstrating a linear relationship between coupling rate and spin number. The experiments show that decreasing the width of the center conductor enhances coupling and cooperativity, leading to promise for scaling hybrid systems to smaller dimensions. The frequency dependence of the coupling rate on the CPW harmonics is observed to be linear, with varying efficiencies.

Strong Parametric Coupling between Two Ultracoherent Membrane Modes

David Halg, Thomas Gisler, Eric C. Langman, Shobhna Misra, Oded Zilberberg, Albert Schliesser, Christian L. Degen, Alexander Eichler

Summary: We demonstrate the parametric coupling between two modes of a silicon nitride membrane by applying an oscillating voltage to a sharp metal tip near the membrane surface. The modes exchange energy periodically and faster than their free energy decay rate when the voltage oscillation frequency matches the mode frequency difference. This flexible method can be useful for rapid state control and transfer between modes, and is an important step towards parametric spin sensing experiments with membrane resonators.

Chemical reactivity under collective vibrational strong coupling

Derek S. S. Wang, Johannes Flick, Susanne F. F. Yelin

Summary: Recent experiments have shown the potential to alter and steer chemical reactions in optical cavities, but the theoretical understanding remains limited. This paper focuses on the unimolecular dissociation reactions of multiple molecules interacting with an infrared cavity mode. The study reveals that increasing the number of aligned molecules can slow down the reaction rate if the cavity mode is resonant with a vibrational mode of the molecules. A scaling relation is also discovered to estimate the onset of reaction rate modification by collective vibrational strong coupling.

Toward Prediction of Financial Crashes with a D-Wave Quantum Annealer

Yongcheng Ding, Javier Gonzalez-Conde, Lucas Lamata, Jose D. Martin-Guerrero, Enrique Lizaso, Samuel Mugel, Xi Chen, Roman Orus, Enrique Solano, Mikel Sanz

Summary: In this study, a novel approach using a D-Wave quantum annealer is experimentally explored to predict financial crashes in a complex financial network. The performance of the quantum annealer in achieving financial equilibrium is benchmarked. The equilibrium condition of a nonlinear financial model is embedded into a higher-order unconstrained binary optimization (HUBO) problem, which is then transformed into a spin-1/2 Hamiltonian with at most, two-qubit interactions. The problem is equivalent to finding the ground state of an interacting spin Hamiltonian, which can be approximated with a quantum annealer. The experiment paves the way for the codification of this quantitative macroeconomics problem in quantum annealers.

Long-Range Free Fermions: Lieb-Robinson Bound, Clustering Properties, and Topological Phases

Zongping Gong, Tommaso Guaita, J. Ignacio Cirac

Summary: In this paper, we study free fermions on lattices in arbitrary dimensions with hopping amplitudes that decay with a power-law. We provide a comprehensive set of constraints on the equilibrium and nonequilibrium properties of these fermions in the regime where the power-law decay is larger than the spatial dimension. Our results include the derivation of an optimal Lieb-Robinson bound and a clustering property for the Green's function. We also discuss the implications of these results on topological phases in long-range free-fermion systems.

An Approach to Interfacing the Brain with Quantum Computers: Practical Steps and Caveats

E. R. Miranda, S. Venkatesh, J. D. Martin-Guerrero, C. Hernani-Morales, L. Lamata, E. Solano

Summary: This report presents a proof-of-concept system that demonstrates how a qubit can be controlled using mental activity. The researchers have developed a method to encode neural signals as instructions for a quantum computer, allowing individuals to issue commands to rotate and measure the qubit using their mental activity. Currently, the system runs on a software simulation, as the hardware and brain activity sensing technology are not advanced enough for real-time control of quantum states. However, this study brings us closer to the possibility of interfacing the brain with real quantum machines as advancements are made in both areas.
